From Anurag: authors should be listed separately in the GS article metadata, similarly to how they are listed in the DC metadata; and they should follow a "firstname lastname" convention rather than a "lastname, firstname" convention. Eg., rather than
<meta name="citation_authors" content="lastname1, firstname1; lastname2, firstname2"/>
... you would have
<meta name="citation_author" content="firstname1 lastname1"/>
<meta name="citation_author" content="firstname2 lastname2"/>
Just waiting for clarification regarding how/whether to use author salutations and affiliations.
(This also applies to OJS.)
